Abstract: ABSTRACT OF THE INVENTION          A machine for forming corrugated plate from a flat sheet defined by a plurality of serially arranged corrugating stands.  At least one stand has cooperating corrugating rolls defined by a plurality of disc shaped dies which, during corrugating, are rotated at dif-fering rates so that the peripheral speed at a selected diameter, of each such disc substan-tially equals the linear speed of the plate being corrugated.  The discs can be constructed of disc shaped die halves, the axial position of which can be varied so as to vary the corruga-tion pitch or the profile while maintaining the pitch constant.  Drives for the corrugating rolls and, in particular, for the disc dies can power rotate all dies or only some of them while others are free wheeling.  Also disclosed are an advantageous construction of the frame which establishes metal-to-metal contact between bearing blocks of the roll shafts so as to rigidify the frame while permitting ready re-placement of the shafts and/or the dies; the construction of the discs of ring halves; the axial mounting of the discs to their shafts and alternative drives for the discs including planetary gear drives, internal ring gear drives, and individual drives.

Abstract: ABSTRACT           An electromagnetic stirrer installed in a conti-nuous stelle casting plant at a distance from the casting path, whereby the stirrer is provided with a guide device on its side facing the casting path for guiding a flexible dummy bar.   In this way the dummy bar, which on account of its degree of play in the casting guide may possibly swing into the stirrer, is kept away from direct access to the structurally relatively weak side of the stirrer which could result in damage.  Furthermore the dummy bar is so guided as to avoid undesirable collision between the dummy bar head and guide rollers.

Abstract: ABSTRACT OF THE DISCLOSURE              CORROSION INHIBITORS, METHOD OF PRODUCING THEM AND PROTECTIVE COATINGS CONTAINING THEM     Corrosion inhibiting particles comprise an inorganic oxide, particularly alumina, having corrosion inhibiting anions, particularly phosphate, chromate or benzoate anions, chemically bound to them. They may be prepared by contacting an oxide containing hydroxyl groups with an acidic solution containing the anions at ambient temperatures.     The particles may be incorporated into protective coatings, e.g. paints based on epoxy resins, alkyd resins or chlorinated rubbers, in amounts up to 80% wt based on dry film weight, giving coatings with up to 4.0% corrosion inhibiting anions.     Release of the anions is by ion-exchange with other anions, e.g. the chloride anions of sea water or salt spray, and does not, as is normal with corrosion inhibiting coatings, depend on water solubility.

Title: Method of impressing and reading out a surface charge on a multilayered detector structure
Inventor: ZERMENO ALFONSO
IPC: H05G1/00
Filed: 1981-02-11
Granted: 1984-02-14
Abstract: A latent charge image is recorded on and reproduced from a multilayered detector by first providing the detector with a uniform surface charge on its photoconductive layer. The photoconductive layer is then biased with an electric field whose polarity opposes that of the uniform surface charge and then the detector is exposed to a modulated radiation flux to cause at least partial discharge of the photoconductive layer. The latent charge image of the modulated radiation flux is thus stored and later read by scanning the surface of the photoconductive layer with a small diameter photon beam to further sequentially discharge the photoconductive layer and the changing electrical potential of this sequential further discharge is detected and processed into a video signal by a processor for storage or display. The unique step of biasing the photoconductive layer with an electric field of opposite polarity to the surface charge greatly increases the efficiency of the detector, the detector's X-ray absorption efficiency, and the scan speed of the readout.

Abstract: ABSTRACT     Circuit for detecting a fault current in an installation where the load (RL) varies upon request.  Current (IS) is converted into a voltage (VS).  During an initialization cycle, means such as a counter, ditital-to-analog converter, comparator, registers (R1 R2) generate a voltage (VC) equal to (VS) at the end of the initialization cycle and a threshold voltage (VD=kVC).  During operation, voltage (VS) is compared with threshold (VD) in order to provide a fault detection indication which is transmitted to the protection circuit by a logic circuit, that is, an AND gate and an OR gate.  During the initialization cycle, protection is obtained by comparing (VS) with a reference voltage in the comparator.  This device is used to protect machines having an expandable configuration.
